The dike will have the following basic characteristics: average height of 22 feet above existing ground, width of crest is 15 feet, 2.25 horizontal to 1 vertical (2.25H:1V) side slopes, upstream slope will be protected with 15-inch layer of riprap over a 12-inch layer of bedding, downstream slope will be hydroseeded. Butterfield Drive, W. Rincon Street, and Auburndale Street will be impacted by the construction of the dike. A concrete floodwall and floodgate will be constructed across Auburndale Street.
